ISA: src vs src_reg

[dthaler]

The source register number field is defined as:

src_reg the source register number (0-10), except where otherwise specified (64-bit immediate instructions_ reuse this field for other purposes)

However, the "64-bit immediate instructions" section has:

Instructions with the BPF_IMM 'mode' modifier use the wide instruction encoding defined in Instruction encoding_, and use the 'src' field of the basic instruction to hold an opcode subtype.

The following table defines a set of BPF_IMM | BPF_DW | BPF_LD instructions with opcode subtypes in the 'src' field, using new terms such as "map" defined further below:

And various tables have a column labeled "src".

These should be src_reg

Also in the appendix, the offset column should probably appear before the imm column.
